TO ALL WHOM IT MAY CONCERN:

Beit known that I, EDWIN KING, of Fredonia, in the State of New York,have invented-an improved Clamping Device for securing field-fence postsand trellis-poles' to 'stone foundations g and I do hereby declare thatthe following is a full and exact description thereof, 'reference beinghad to the accompanying drawings,`

making a part of this specification, in which-f Y i y Figure 1 is aperspective view of a post for supporting the panels of commonldeld-feuces, provided with my clamp device for securing it to aboulder. t

Figures 2 and 3, front elevationand vertical section through line a b.

Figure 4, a perspective view of Va trellis-pole, provided with said,clamp device, showing the I uannerrof` lowering the pole The sameletters of reference indicating similar parts in all the figures. i

0n farm lands, in many sections of country, boulders and other stone areoften found in great plenty, so l that they are frequently used forsupporting fence-posts or the sills on which the posts stand.

The object of this invention is to supply a simple device by which thepost itself `can beexpeditiously and thoroughly secured to suchfoundations, with but little outlay of time and money; and as a verylarge amount of posts are usually required in the fencing in of iields,it becomes au important object with the owner or occupier of the landthat any device for the purpose should be at once cheap, simple, andVeilic'ient. These qualities, it is believed, can be realized more fullyby this inveuton'thau by any of the methods now in use; 3 y i and shouldit be required to take up the posts for removal it will be seen, byinspecting the drawings, that itt,

can be very readily accomplished, In the case of trellis-poles forsupporting grape-vines, as shown in fig. 4,

4the pole can be readily lowered to the ground so as to allow the vineto be covered up to protect it from frost. p

In some localities this is a necessity with vine-growers, and istherefore often practised. y

The following is a description of the construction and operation of myinvention: A A', iig. l, is Va pair of clamps, of the angular formshown, the foot of each having a slit or notch, BB, and `bolt-holesC,`iig. 2on1 l 'the upright portion. The edges or corners of the saidupright part are turnethas at VD. 0n the innerfuce of I each clamp isalong knife-edge projection, E, igfZ, which cuts into a correspondinggroove on each side of,`

the post F. The said clamps are fastened to the post by a bolt, D',passing fromone to the other, through the post. It will be seen thattheturned edges D, and knife-edge projections E, secure the clampsveryfirmly tof` y the post, so that they cannot easily become loose. Thepost is secured to the boulder -or other stone by means` of the nuts ofthe screw-bolts, which are leaded Ainto it, as seen in iig. 1. The postscan `be readily removed` from the stone, or thetrellisfpole lowered, bysimply unscrewing the nuts, as seen in iig. 4.

I am aware that clamping devices, singly and in pairs, are in common usefor various purposes; such, therel fore, I do not lay claim to, but Iclaim the improved construction and adaptation of my` said device tofieldt fence posts and trellis-poles, so as to operate in themannershow, and as a cheap and eihcie'nt device for` the..

purpose stated.

What I claim, therefore, and desire to secure by Letters Patent, is-

I claim the improved clamp A, provided with the return edges D D,knife-edge projectionyE,'sl`ot.B, bolt-` hole C, and bolt D', incombination with fence-posts and trellis-poles, so as to operate `in themanner substantially as herein specified and for the purpose set forth.i l l i EDWIN KING'.
